Charitable event noble arranged (10)
I believe the answer is:
benevolent
'charitable' is the definition.
('benevolent' can be similar in meaning to 'charitable')
'event noble arranged' is the wordplay.
'arranged' indicates anagramming the letters.
'event'+'noble'='eventnoble'
'eventnoble' anagrammed gives 'BENEVOLENT'.
(Other definitions for benevolent that I've seen before include "Showing kindness" , "Well-meaning, kindly" , "Philanthropic" , "Well disposed" , "Well meaning, kindly" .)
